Like the unseen solar observatory STEREO-B spacecraft trailing Earth and passing through the Earth-Sun L4 point, STEREO-A is visualized here at L5 on August 1st this year. Both vehicles have begun looking for planetary materials that may have formed or collected in these vast zones of neutral gravitational forces. Volunteers are requested to help search resulting images online. See news here and here. Credit: NASA/GSFC Scientific Visualization Studio.
